  • I don’t know if i should be posting this here or on the Big Easy Driver Page, but i’m hoping somebody will be able to provide me with some insight. I have been able to get it running using the example provided on Brian’s website. The issue i am having, is that the motor will only run smoothly when the current is being limited much lower than what the motor is capable of. When i adjust the current limit higher the motor will keep losing power entirely (i.e. the shaft can be freely spun until it starts spinning again). Is this an issue with the supply i am running it off of? The power supply i am using is a 19V supply rated at 4.7 amps.

No public wish lists :(
